Question about soccer tryouts?

I suck! I've totally lost faith in myself. See, the thing about our coach is that he takes points! We've had like three drills that he took points on, and i hate pressure, so i ended up sucking , and failed misserably. With no pressure, i'm pretty okay, but with pressure i look soccer illiterate. Our tryouts have been like 3 weeks long, and i'm f-ing bombing them. I'm really good when i've actually made the team, but tryouts are like a huge exam to me, and i just hate pressure, and that's what tryouts are to me-'pure pressure'. Any tips, should i just stop, because i think i'm already too low to pull myself up. I'm so agrivated.
